COMBINATION LETTER-SHEET AND ENVELOP.

To all whom "it may concern:

Be it known that I, ANDERS KRAMER, sub ject of the Emperor of Russia,and now residing at No. 446 Sixth avenue, in the borough of Brooklyn,county of Kings, city and State of New York, have invented a new anduseful Combination Letter-Sheet. and Envelop, of which the following isa specifica' tion.

The invention relates to an improvement in a combination letter sheetand envelop and has for its objects: to provide an im proved combinationsheet and envelop constructed from a letter sheet or sheets, commonlyused in correspondence, which sheet or sheets, after being folded asdescribed in detail below, are sealed by means of strip or strips ofgummed tape, with the object of: l. Securely and effectively sealing thecontents of said sheet or sheets without the use of any additional paperor cloth commonly known as envelop, in such manner as not to permit oftheir inspection. 2. Exposing the name and address of the addressee insaid letter sheet or sheets contained so as to avoid the necessity ofaddressing the addressee twice. 3. Exposing the name and address of theaddresser or sender, if any, contained in the letter head of said sheetor sheets, so as to avoid the necessity of indicating the same again. 4.Exposing such other matter, if any, as may be contained in the letterhead, so as to advertise the contents thereof. 5. Preserving the postmark, if any, on the letter sheet itself, as evidence of the matter insuch post mark contained. '6. Making possible the use of stamped lettersheets to be manufactured and sold by government. I attain these objectsby constructing the combination letter sheet and envelop in the mannerillustrated in the accompanying drawings wherein:

Figure l is an illustration of my improved combination letter sheet andenvelop in process of being folded. Fig. 2 is another view of the sheetin further process of folding. Fig. 3 is a front view of a sheetcompletely folded and sealed. Fig. 4 is a rear View of the folded sheetshown in Fig. 3, and Fig 5 is the sealing strip used on the foldedsheet.

Fig. 1 is a view of a letter sheet commonly used in correspondence,beginning to be folded so as to construct the combination letter sheetand envelop. The letter sheet Specification of Letters Patent.

in practice reserved for the name and address of the sender oraddresser, and for such other matter as may be contained in a letterhead, or may remain vacant. Spaces 1)., E., F. and G., are vacant, andare tobe used for purposes hereinafter described; space J. is inpractice reserved for the stamp, if any; space H. being all the spacebelow the transverse folding line 12 is in practice reserved for thecontents of the letter proper.

Fig. 2. is a view of a letter sheet after it has been folded along thetransverse folding lines 56, 3%, 12, so as to expose the portion and allthe space above the transverse folding line 12, and after it has beenbegun to be folded along the longitudinal fol-ding lines, ab, ccZ.

The improy ed letter sheet and envelop is constructed as follows: Theletter sheet is folded along the transverse folding lines 56, 34, 12,with the object of covering up the space H. below the transverse foldingline 12, exposing the entire space or portion above the transversefolding line 1-2. The letter sheet so folded is then further foldedalong the longitudinal folding lines ab, 0(Z, the beginning of whichfolding is illustrated in Fig. 2., till the longitudinal edges of spacesD. and E. meet, so as to have on one side of the folded sheet spaces A.F. Gr. and J. and on the other side spaces B. C. and spaces D. E., whichtwo last spaces are now contiguous to each other with their longitudinaledges. To the letter sheet so folded a moistened strip of gummed tape orribbon is applied in such a manner as to cover up the spaces D. and E.,allowing said moistened strip to lap over so as to cover spaces F. andG., as well, as illustrated in Figs. 3 and 4.

In practice the stamp, if any, is placed in the space J.

The combination letter sheet and envelop so constructed does not allowexamination of the contents of the letter proper, without breaking ortearing of the tape and it also attains all the other objects heretoforementioned.

In constructing the combination letter sheet and envelop, the number offolds below the transverse folding line 1*2 need not be limited toany-particular number, so long as the space below the said linecontaining the letter proper is completely covered, and will depend inpractice on the size of the combination letter sheet and envelopdesired. The construction of the combination letter sheet and envelopmay also be modified by gumming the spaces D. E. F. and G. of the lettersheet and applying to them strip or strips of ungummed tape, or byattaching a strip of gummed tape to either the space D. or 15., so thatit extends outside of the transverse and longitudinal edges of the spaceto which it is attached, in such a manner that when the letter sheet isfolded as herein previously described, the extended portion of said gum-.med tape shall cover up spaces E. F., and G.

if the said gummed tape is attached to space 1)., or spaces D. F. and G.if said gummed tape is attached to space E.

A number of letter sheets, one on the top of each other, may be treatedin the same way as a single sheet for the purpose of constructing thecombination letter sheet and envelop.

I would note that if desired, the name and address of the addresser maybe placed in the left hand corner of space A so that in the completelyconstructed combination letter sheet and envelop, it appears on thefront or address side of it.

I am aware that prior to my invention a combination letter sheet andenvelop has been made, which attains some of the objects hereinmentioned. My invention, however, differs in structure and arrangementof parts essentially from all previous inventions in the same class.

I do not claim the combination letter sheet and envelop broadly, but

I claim:

1. A combination letter sheet and envelop comprising a sheet of paperfolded along a line parallel to and suitably near the top edge of thesheet forming an upper part and a lower part, the lower part folded uponitself to entirely conceal it beneath the said upper part, the exposedside of said upper part constituting the letter head, the inner side ofsaid upper part and both sides of said lower part constituting the bodypart for retaining the writing or printing constituting the letter, thesaid folded sheet finally folded along lines at right angles to thefirst folds completely concealing the body part and exposing on one sidethe central partof the letter head for the desired addresses and postagestamp, and exposing on the other side the end portions of the letterhead, and a seal securing the edges of said end portions together.

2. A combination letter sheet and envelop comprising a sheet of paperfolded along a line parallel to and suitably near the top edge of thesheet forming an upper part and a lower part, the lower part folded uponitself to entirely conceal it beneath the said upper part the exposedside of said upper part constituting the letter head, the inner side ofsaid upper part and both sides of said lower part constituting the bodypart for retaining the writing or printing constituting the letter, thesaid folded sheet finally folded along lines at right angles to thefirst folds completely concealing the body part and exposing on one sidethe central part of the letter head for the desired addresses and thepostage stamp, and exposing on the other side the end portions of theletter head, and a seal securing the edges of said end portionstogether, the seal having its ends folded over and glued upon the saidcentral part of the letter head for a suitable distance thereon.
